+Basic use of EmailChecker with built-in throwaway email list:
+
+```php
+<?php
+
+require __DIR__.'/vendor/autoload.php';
+
+use EmailChecker\EmailChecker;
+
+$checker = new EmailChecker();

+$checker->isValid('foo@yopmail.com'); // false
+```

+```php
+<?php
+
+use EmailChecker\EmailChecker;
+use EmailChecker\Adapter;
+
+$checker = new EmailChecker(new Adapter\ArrayAdapter(array(
+    'foo.org',
+    'baz.net'
+)));
+
+$checker->isValid('foo@bar.org'); // true
+$checker->isValid('foo@baz.net'); // false
+```
